Ground'dointConner-iionior iilleetric blondine tors, of which the following o specification.

My invention relates to ii .new and nseicui ground connection und consists einen' :ind novel ineens for connecting the sinne with :i pine, rod or other snit-.dile conductor.

it further consists of other novel tentures of construction, all as will be liei'einefter fully set forth.

Figure 1 represents a perspective View oi' s. ground connection embodying my invention. Fig. 2 represents s sectioned View online x Fig. l.' Fig. 3 reolresents e perspective view of portion of ti e connection in detached position.

Similar numeriiis of reference indicate eerres bonding parts in the iigures.

i eferring to the drawings. i. lieve found in pinetice, in the ground eonneetions for electric conduetors now in use, that, owing to the iiriengenient of the tightening;r ineens, it is ent to destroy the pipe or other support to which the connection is fastened. My invention is designed to overcome this defect and to liroyide ay newr end novei connecting ineens, and in the drawings, I have shown e construction for carrying out my invention, but it will be evident that the urrengenient of the parts may be varied and other instru mentalities may be employed which will come within the scope of my invention and do not therefore desire to be limited in every in.- stance to the exact construction es herein shown sind described but desire to Ineke such changes as may be necessary.

1 designates the body portion of my connection having the side pistes 2 and 3 and to one of which, in the present instance 3, is connected n bond 4i in en 7 suitable manner, as for exempie by the boits 5. The band 4 is preferably iexible sind of any suitable metal or other good conducting instel-isi, said band havin a uraiity oi openings 6 at suitable inteivaii t ierein.

In the body l, l provide e slot or openingf 7 which is adapted to 'receive the free end of the band after the seme is appiied to the pipe 8 or other suitable support. In' the side plates 2 and 3, l provide suit-abie openings 9 through which is adapted to be passed, e
